Correct UseThe safety system MGB is an electromagnetic interlock device without guard locking.

The system comprises at least one interlocking module MGB-L0-AR-... and one handle module MGB-H...

The interlocking module MGB-L0-AR-... can be integrated into a switch chain for the safety system CES-AR or operated as a separate system.

In combination with a separating safety guard, this safety component prevents dangerous machine movements from being performed for as long as the safety guard is open. A stop command is triggered if the safety guard is opened during the dangerous machine function.

For the control system, this means that

starting commands which cause hazardous situations must become active only when the safety guard is in the protective position.

Before safety components are used, a risk assessment must be performed on the machine in accordance with

EN ISO 1�849-1, Safety of machinery. Safety related parts of control systems. General principles for design, Annex B

EN ISO 141�1, Safety of machinery. Risk assessment. Principles.

Correct use includes compliance with the relevant requirements for installation and operation, in particular

EN ISO 1�489-1, Safety of machinery. Safety related parts of control systems. General principles for design

EN 1088, Safety of machinery. Interlocking devices associated with guards. Principles for design and selection

EN 60�04-1, Safety of machinery. Electrical equipment of machines. General requirements.

The safety system MGB can only be combined with the intended modules in the MGB system family.

On the modification of system components, EUCHNER provides no warranty for safe function.

Connection of several devices in a CES-AR switch chain is permitted only using devices intended for series connection with the CES-AR. Please check this in the operating instructions of the respective device. For detailed information on opera-tion in a CES-AR switch chain, please see the related CES-AR system manual.

Important!

The user is responsible for safe integration of the device in a safe overall system. For this purpose the overall system must be validated, e.g. in accor-dance with EN ISO 1�849-�.The permissible operating parameters must be observed for correct use (see Technical data).If a product data sheet is included with the product, the information on the data sheet applies in case of discrepancies with the operating instructions.


4

Important!

In the estimation of the PL for the overall system, a maximum value of 100 years can be assumed for the MTTFd according to the limit value in EN ISO 1�849-1:�008, Section 4.5.�. This corresponds to a minimum value for the PFHd of �.47 x 10-8/h.When up to 10 devices are connected in series, these limit values can be assumed for the entire switch chain as a subsystem. As a subsystem, this switch chain achieves PL e.

Exclusion of Liability and WarrantyIn case of failure to comply with the conditions for correct use stated above, or if the safety instructions are not followed, or if any servicing is not performed as required, liability will be excluded and the warranty void.

General Safety InstructionsSafety switches fulfill personal protection functions. Incorrect installation or tamper-ing can lead to fatal injuries to personnel.

Check the safe function of the safety guard particularly

after any setup work

after the replacement of an MGB component

after an extended period without use

after every fault

Independent of these checks, the safe function of the safety guard should be checked at suitable intervals as part of the maintenance schedule.

Warning!

Loss of safety function in the event of incorrect connection or incorrect use. Safety switches must not be bypassed (bridging of contacts), turned away, removed or otherwise rendered ineffective.On this topic pay attention in particular to the measures for reducing the pos-sibility of bypassing from EN 1088:1995+A�:�008, section 5.7.The switching operation is only allowed to be triggered by the intended han-dle module MGB-H... that is positively fastened to the safety guard.

The device is only allowed to be installed and placed in operation by authorized personnel who are familiar with the correct handling of safety components who are familiar with the applicable EMC regulationswho are familiar with the applicable regulations on health and safety who have read and understood the operating instructions and the system manual


5

Important!

Prior to use read the operating instructions and the system manual, and keep these in a safe place. Ensure the operating instructions and the system manual are always available during mounting, setup and servicing. EUCHNER cannot provide any warranty in relation to the readability of the CD for the storage pe-riod required. For this reason you should archive a printed copy of the system manual. If you should lose the operating instructions or the system manual, you can download these documents from www.EUCHNER.de.

FunctionTogether with a handle module, the interlocking module makes it possible to interlock moveable safety guards. The combination also serves as a mechanical door stop at the same time.

The following switch-on condition applies for the safety outputs OA and OB (see also System status table):

Safety guard closed

Bolt tongue inserted in the interlocking module

Both safety inputs (IA and IB) must be on

The interlocking module detects the position of the safety guard and the position of the bolt tongue.

The bolt tongue in the handle module is extended and retracted into the interlocking module by actuating the door handle.

Protection Against Environmental EffectsLasting and correct safety function requires that the system must be protected against foreign bodies such as swarf, sand, blasting shot, etc., which can become lodged in the interlocking and handle modules. For this purpose a suitable instal-lation position should be selected.

Cover device during painting work!


1�

Electrical ConnectionWarning!

In case of an error, loss of the safety function through incorrect connection.To ensure safety, both safety outputs (OA and OB) must always be evaluated.The monitoring outputs O1 ... O4 must not be used as safety outputs.Lay the connection cables with protection to prevent the risk of short cir-cuits.

Caution!

Risk of damage to equipment or malfunctions as a result of incorrect connec-tion.Do not use a control system with pulsing or switch off the pulsing function in your control system. The device generates its own clock signal on the output lines OA/OB. A downstream control system must tolerate these test pulses, which may have a length of up to 1 ms. The pulses are also present when the safety outputs are switched off. De-pending on the inertia of the connected device (control system, relay, etc.), this can lead to short switching processes.The inputs on an evaluation unit connected must be positive-switching, as the two outputs on the safety switch deliver a level of +�4 V in the switched-on state.All the electrical connections must either be isolated from the mains supply by a safety transformer according to EN IEC 61558-�-6 with limited output voltage in the event of a fault, or by other equivalent isolation measures.For use and operation as per the requirements, a power supply with the feature "for use in class � circuits" must be used. The same requirement ap-plies to the safety outputs.Alternative solutions must comply with the following requirements:a) Electrically isolated power supply unit with a max. open-circuit voltage of �0

V/DC and a limited current of max. 8 A.b) Electrically isolated power supply unit in combination with fuse as per UL�48.

This fuse should be designed for max. �.� A and should be integrated into the �0 V/DC voltage section.

All electrical outputs must have an adequate protective circuit for inductive loads. The outputs must be protected with a free-wheeling diode for this pur-pose.Power devices which are a powerful source of interference must be installed in a separate location away from the input and output circuits for signal pro-cessing. The cable routing for safety circuits should be as far away as pos-sible from the cables of the power circuits.To prevent EMC problems, it is imperative you follow section Notes on cable laying, page 15.

Important!

If the device does not appear to function when operating voltage is applied (e.g. green DIA LED does not flash), the safety switch must be returned uno-pened to the manufacturer.To ensure the stated degree of protection IP67 is achieved, the cover screws must be tightened to a tightening torque of 1 Nm.Tighten screw for the cover for the mechanical release to 0.5 Nm.


14

Safety in case of faultsThe operating voltage UB is reverse polarity protected.

The contacts IA/IB and OA/OB are short circuit-proof

A short-circuit between IA and IB or OA and OB is detected by the switch.

A short circuit in the cable can be excluded by laying the cable with protection.

Fuse protection for power supplyThe power supply must be provided with fuse protection depending on the number of devices and current required for the outputs. The following rules apply here:

Max. current consumption of an individual device Imax

Imax = IUB + IUA + IOA+OB

IUB = Device operating current (80 mA)

IUA = Load current of monitoring outputs O1, O� and O4 (� x max. �00 mA) + control elements

IOA+OB = Load current of safety outputs OA + OB (� x max. �00 mA)

Max. current consumption of a switch chain Σ Imax

Σ Imax = IOA+OB + n x (IUB + IUA)

n = Number of devices connected

Assignment of the currents to the fuse circuits

IUB 80 mA

IOA+OB (� x max. �00 mA)

IUA

IControl elements = max. �0 mA

Requirements for connection cablesCaution!

Risk of damage to equipment or malfunctions as a result of unsuitable connec-tion cables.On the usage of other connection components, the requirements in the fol-lowing table apply. EUCHNER provides no warranty for safe function in case of failure to comply with these requirements.

Observe the following requirements for the connection cables:

Information on operation in a CES-AR switch chainSystem timesThe interlocking module has longer response times than a CES-AR switch (see Technical data and diagram of Typical system times, Figure 19 and �0).

Position in a CES-AR switch chainThe interlocking module must be the last device in the CES-AR switch chain (see Figure 18).

Important: lay cables in a common harness

Figure 18: Position in a CES-AR switch chain

Output currentThe safety outputs on the interlocking module have a lower maximum output cur-rent than a CES-AR switch (see Technical data).

Number of devices in the switch chainsIn a pure MGB switch chain a maximum of ten devices can be connected in series. In mixed switch chains (e. g. together with CES-AR) the maximum number of devices is also reduced to ten.

Setup

Teach-in operationThe handle module must be assigned to the interlocking module using a teach-in function before the system forms a functional unit.

During a teach-in operation, the safety outputs are in high-resistance state, i.e. the system is in the safe state.

Important!

The interlocking module disables the code for the previous handle module if teach-in is carried out for a new handle module. Teach-in is not possible again immediately for this module if a new teach-in process is carried out. The disabled code is deleted again in the interlocking module only after a third code has been taught.The interlocking module can only be operated with the last handle module taught.If the locking module detects the learned or a locked handle during learning readiness, the learning readiness is ended immediately and the locking mod-ule enters normal mode or indicates a fault.If the bolt tongue is in the operating distance for less than 60 s, the handle module is not taught.

Teaching in handle moduleFit handle module.

Close safety guard. Check for correct alignment and distance using the mark-ing on the interlocking module and re-adjust if necessary.

Insert bolt tongue in the interlocking module.

Apply operating voltage to the interlocking module.

The green LED (DIA1) flashes quickly (approx. 10 Hz)

A self-test is performed during this time (approx. 8 s). After this, the LED flashes cyclically three times and signals that it is in standby state for teach-in. Standby state for teach-in remains active for approx. � minutes.

Teach-in operation starts, green LED (DIA1) flashes slowly (approx. 1 Hz). Dur-ing teach-in, the interlocking module checks whether the handle module is a disabled handle module. Provided this is not the case, the teach-in operation is completed after approx. 60 seconds, and the green LED (DIA1) goes out. The new code has now been stored, and the old code is disabled.

To activate the handle module's code from the teach-in operation in the inter-locking module, the operating voltage must then be switched off at the inter-locking module for min. � seconds. As an alternative, �4V can be applied to the input RST for min. � seconds.

Mechanical function testIt must be possible to easily insert the bolt tongue in the interlocking module. To check, close safety guard several times and actuate door handle.

If available, check function of the escape release. It must be possible to operate the escape release from the inside without excessive effort.


�1

Electrical function test

Warning!

On usage in a CES-AR safety chain, also follow the procedure for the function check in the related CES-AR system manual.

Switch on operating voltage.

The interlocking module carries out a self-test. The green LED (DIA1) flashes for 8 s with 10 Hz.

Close all safety guards and insert the bolt tongue into the interlocking mod-ule.

The machine must not start automatically.

Enable operation in the control system.

Actuate the door handle.

The machine must switch off. The yellow LED (STATE) on the interlocking mod-ule flashes at regular intervals.

Open the safety guard. The yellow LED (STATE) goes out.

Close the safety guard again.

The machine must not start up again immediately.

Enable operation again in the control system.

Repeat steps �-6 for each safety guard.
